How many moles of oxygen are produced when 26.5 mol of aluminum oxide are decomposed?

1 answer:

7 0

The balanced chemical reaction is written as:

<span>2Al2O3 = 4Al + 3O2

We are given the amount of aluminum oxide used in the reaction. This will be the starting point for the calculations. We do as follows:

26.5 mol Al2O3 ( 3 mol O2 / 2 mol Al2O3 ) = 39.75 mol O2 produced</span>
